The LYMAN BLACK POWDER HANDBOOK & LOADING MANUAL , 2nd Edition shows data for a .44 cap and ball pistol with a 8 inch barrel.
You didn't say what type of black powder but the Lyman book gives the following for GOEX 3Fg under a .451 dia roundball.
20 grains= 640 fps = 610 fps at 25 yards
25 grains = 727 fps = 692 fps at 25 yards
30 grains = 794 fps = 754 fps at 25 yards
With Pyrodex P the velocities with the same diameter roundball were:
20 grains = 739 fps
25 grains = 847 fps
30 grains = 896 fps

Those Lyman manual numbers are pretty accurate. I've run a number of cap and ball loads over a chronagraph and they come very close to what Lyman publishes. My brass frame Colt in 44 loaded with 25 grains of Pyrodex P is the ballistic equivalent to a factory standard loading of the .38 special. Not super impressive but sure enough a killer. All the cap and ball guns make good trail and camp guns.

Just out of curiosity, does the hand book have a listing for 50 and 55 grains in either a 8 or 9 inch barrel? Reason that I ask is that I did get a chance to break the sound barrier with my 3rd Model Dragoon using 45 grains of 3Fg Goex, a wonder-wad and a .454 ball. Never got to chrono the Walker though...
Thanks and have a great New Years!

Before that 600 to 650 fps and (~140gr) soft lead round ball with 25gr of 3Fg sounds on the wimpy side...
...Remember that the "already made up" paper cartridges with soft conicals had MUCH less powder with maybe a 30% increase in projectile weight.
Also if that pistol of yours has a brass frame, I wouldn't let the charge exceed 20 to 22gr of FFFg with round ball and I wouldn't recommend conicals in a brass framed piece at all.
Round balls are what these C&B revolvers work best with, and they have plenty of "punch" relative to their limitations.

PS I've used quite a bit of Pyrodex over the years and it will work suitably--provided the appropriate equivalents for maximum charges are adhered to.
